A Russian warship early on Friday twice violated Danish territorial waters north of the Baltic Sea island of Bornholm where a democracy festival attended by senior lawmakers and business people was taking place, the Danish Armed Forces said.
The Russian warship entered Danish waters without authorization at 0030 GMT on Friday and again a few of hours later, the armed forces said in a statement. The warship left after the Danish navy established radio contact, it said.
"A deeply irresponsible, gross and completely unacceptable Russian provocation in the middle of #fmdk," Denmark's Foreign Minister Jeppe Kofod said, referring to the Democracy Festival of Denmark.
The Russian ambassador had been summoned, he added.
